Free fun things in Atlanta include the Fernback Science Center, Piedmont Park, Centennial Olympic Park and Underground Atlanta. The Fernback Science Center offers free admission to the 9,000-square-foot exhibit hall, the library and a 65-acre forest. Admission is charged for shows at the center's 500-seat Jim Cherry Memorial Planetarium.
Piedmont Park covers 211 acres and is open year round. The Atlanta Dogwood Festival and Atlanta Pride Festival are held in the park each year, but most activities are free. Picnic shelters, jogging paths and an off-leash dog park are available. Fishing is available in Lake Clara Meer, but a Georgia fishing license is required.
Centennial Olympic Park is in the heart of downtown Atlanta. The 21-acre family-friendly park offers free concerts, Family Fun Days, and an annual Fourth of July Celebration. The annual Holiday in Lights Festival, along with its ice-skating rink, is also free. Even during quiet times, the park offers pathways to walk or jog past sculptures and manicured grounds.
Underground Atlanta opened in 1969 and is literally a city underneath the downtown core. Admission to the area is free. The subterranean venue covers six city blocks and has 225,000 square feet of shopping, restaurants and entertainment venues spread out over three levels.
